    Abstract
    Hospho-olivine material, LiMnPO4 was identified as a cathode material that promises for the next generation of Lithium-ion batteries and has been successfully synthesized by solid-state method with Li2Co3, 2MnO2, 2NH4H2PO4 as raw material. Effect of concentrations of initial precursors on calcination temperature (400 - 800 ° C) flowed with nitrogen. The purity and composition of the phase was verified by X-ray diffraction analysis (XRD), electron scanning microscopy (SEM), spectroscopy, Dispersive Energy X-ray Analysis (EDS) , Raman spectrum. General investigations show that there is a correlation between the precursor concentration, calcination temperature and sintering temperature which can be exploited for the design of the next generation lithium-ion battery.

Pengaruh konsentrasi prekursor awal pada suhu kalsinasi (400 - 800 ° C) mengalir dengan nitrogen. Kemurnian dan komposisi fase diverifikasi oleh analisis difraksi sinar-X (XRD), mikroskop pemindaian elektron (SEM), spektroskopi, Energi X-ray Analisis Dispersif (EDS), spektrum Raman. Investigasi umum menunjukkan bahwa ada korelasi antara konsentrasi prekursor, suhu kalsinasi dan suhu sintering yang dapat dimanfaatkan untuk desain baterai lithium-ion generasi berikutnya.
